This invention relates to tractor hitches and more particularly to a device for effecting the withdrawal and insertion of the hitch pin.

It is an object of the present invention to provide a hitch device for connectin trail behind 2 Claims. (01. 2s0-ss.15)

implements to a tractor wherein the pin can be withdrawn or inserted from a point upon the tractor without the necessity ofv getting ofithe tractor, and whereby this means has sufficient leverage so that it can be eifected withsa'minimum of efiort and without requiring that devices be provided to strike the hitch pin so as to place a burr thereon and make it difiicult to be used thereafter. i

It is another object ofthe present invention to provide a device for operating the hitch pin of a tractor implement which while being readily accessible can be broken down so that its parts will not interfere with the operation of the implement or be in the way of the operator of the tractor and further whereby an adjustment can be made of the arm which normally extends upwardly so as to suit the particular operator of the tractor.

For other objects of the invention and for a better understanding of the same, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a side elevational view of a portion of a tractor having a drawbar and with the implement tongue connected to the same by a hitch pin operated by a device embodying the features of the present invention.

Figure 2 is an enlarged perspective View of the implement tongue removed from the tractor drawbar and showing the operating device for the hitch pin mounted thereon.

Figure 3 is a cross sectional view taken through portions of the handle structure of the hitch pin operating device.

Referring now to the figures, I represents a tractor having a rear wheel structure II with an operators station or seat I3 located thereon.

From the rear of the tractor there extends a tractor drawbar I l having holes therein adapted to receive a hitch pin ,I5 whereby to connect a tractor drawn implement to the tractor by means of a tongue I6 having vertically spaced side plates I? and It with holes in their forward ends adapted also to receive the hitch pin 15 whereby to make the connection of the tongue with the drawbar I4. I'he forward ends of the vertically spaced plates I7 and I8 are pinched together so as to permit the use on a short hitch pin I 5.

. p p 2 VI v The top piece I! has an upwardly extending lug I9 to which is pivoted a member ZI by means of a bolt pivot pin extending through the member 2| and the lug I9. This bolt pivot pin is indicated at 22L The forward end of the member 2I is connected by a rivet 23 to the top of the hitch pin I5. The forward end of the member is also curved upwardly to provide a vertically extending portion 24.

To-thisvertically extending portion 24 there is connected an adjustable armlstructure indicated generally at 25. This arm structure 25 includes a member 26 connected to the upper end ofthe vertical portion 24 by means of a bolt 21 and a knurled nut 28. The member 26 has v serrated portions 29 thereon cooperating with comp1ementary serrated portions 3| on the vertical portion 24. A spring is disposed between the knurled nut 28 at the side face of the portion 24 whereby to permit the pivotal adjustment of the member 26 on the portion 24 at any time it is desired to swing the handle structure 25 rearward- 1y to an out-of-the-way position as indicated in dotted lines 32 of Figure 2.

In order that the handle structure 25 can be adjusted to different lengths, there is provided a second member 22 having a series of holes 34 extending along the length of the same and adapted to have bolt means 35 and 36 extended through them so as to retain the member 33 in an adjusted position upon the member 26. Similar holes can be provided upon the member 26. The member 33 has a hand engaging portion 37. When the handle structure 25 is in the raised position it can be seen that it is readily accessible to the operator upon the operators station I3. The structure 25 can be elongated to have different lengths so that the operator who may have short arms can more easily reach the hand engaging portion 31.

At times when it is desired to hitch the implement to the tractor drawbar or to unhitch the same the hand of the operator grasps the hand engaging portion 31 and it is pivoted upwardly about the pivot pin 22 thereby withdrawing the hitch pin I5 from its engagement with the pieces I1 and I8 and the drawbar I4. A spring 38 connected between the forward end of the member 2| and to the forward end of the piece I1 will tend to hold the pivoted structure downwardly as when the hitch pin I5 is in place.

Having now described my invention, I claim:
